The locomotives with tender 81-88 of the Chemin de fer de Smyrne-Cassaba et Prolongements (SCP) were delivered in 1926 by the Corpet-Louvet locomotive factory in La Courneuve for use on the company's route network from Izmir . Together with SCP, the locomotives went to the Turkish state railway TCDD in 1934, which decommissioned the last machines in the early 1980s.

history

After the First World War and the subsequent Greco-Turkish War , the SCP's locomotive fleet was outdated and in need of renewal due to a lack of maintenance. The company therefore procured several series of new locomotives in the years following the Lausanne Treaty . These included the eight “Decapods” supplied by Corpet-Louvet with a 1'E wheel arrangement, which were the most powerful locomotives ever procured by SCP. Up until then, Corpet-Louvet had primarily acted as a manufacturer of narrow-gauge locomotives , with the SCP locomotives, as far as is known, the company manufactured the largest steam locomotives it had ever produced.

Due to the weak superstructure, an axle load of 13.2 tons had to be maintained. In order to still accommodate the necessary power, the 1'E wheel arrangement was chosen, with which a high friction mass was possible with a low axle load. After delivery, the locomotives were mainly used on the Manisa – Bandırma railway line . They also used the other main line of the SCP, the Izmir – Afyonkarahisar railway . In 1934 the SCP was nationalized and the locomotives went to the Turkish State Railways TCDD . They initially ranked them with the numbers 56.011-018 in their inventory. From 1937, the TCDD received the first copies of their new standard locomotives of the 56.001–166 series , which initially occupied the number block from 56.021. In 1940 the older SCP machines were renumbered 56,911–918 and their previous numbers were taken over by the other standard locomotives delivered from 1940.

After the transition to the TCDD, the area of ​​application of the locomotives expanded. They took over traction services on the İzmir – Eğirdir railway of the Ottoman Railway Company (ORC) from Izmir to the east and its branches from 1935, which also belonged to the TCDD . The locomotives were used in a variety of ways, in addition to passenger and freight trains on their main lines, they took over pushing services and deployments in Banliyö Trenleri in the suburbs of Izmir. The powerful locomotives, popular with the staff, remained in service for over 50 years; the last ones were retired in 1982.

Four locomotives in the series have been preserved so far. The locomotives 56.914 and 56.917 are in the Çamlık Railway Museum as museum locomotives, the engines 56.911 and 56.912 at the stations of Nazilli and Alaşehir .

technical features

The locomotives were designed as technically comparatively simple two-cylinder superheated steam locomotives and were considered to be relatively small but modern machines for their wheel arrangement . They received a feed water preheater and piston valve . The leading axle is mounted in a Bissel frame.
